Myst variables

As a preliminary step, this page lists Myst variable numbers and their meaning to aid the reverse engineering process. For the moment this is only based on interpretation of VIEW conditional images.

The scope of variable numbers seem to be local to the single stack (age). That is, variable 0 in Stoneship and variable 0 in Mechanical are independent. Note that this raises the question of where global game info is kept.
